With reference to James Webb Telescope, consider the following statements:1. It will be situated near the second Lagrange point of the Earth-Sun system. 2. It will be able to look back over 13.5 billion years to see the first stars and galaxies of the early universe. 3. The telescope works in the infrared spectrum. Which of the statements given above is/are correct?

[A] 1 and 2 only

[B] 2 and 3 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: D

Notes:

All statements are correct

James Webb Telescope is an international collaboration between NASA, European Space Agency(ESA), and the Canadian Space Agency.
Once in space, the telescope will be situated near the second Lagrange point of the Earth-Sun system, which is around 1,500,000 km from Earth and directly opposite the Sun.

The telescope will be able to look back over 13.5 billion years to see the first stars and galaxies of our early universe.
The telescope works in the infrared spectrum, collecting infrared light from the object it is focused on.
But why infrared? Infrared light is electromagnetic radiation with longer wavelengths than visible light. This particular trait of the telescope would help it look farther back in time more effectively than other telescopes. It will also help scientists look into the atmosphere of stars, which is usually shrouded with dust and gas during formation.
